This study explored how the promotion points system for teachers contributing to the prevention and resolution of school violence operates in schools and how teachers perceive it through in-depth interviews. The results showed that teachers' backgrounds influence the selection of promotion point recipients, and there is a tendency to emphasize fairness based on performance for promotion rather than the prevention and resolution of school violence. Furthermore, the system was found to have adverse effects such as inducing competition and conflict among teachers, undermining the cohesion among school members.
